"On a NFS mounted on my PC your LS_COLORS tweak actually degrades the performance"

Run "strace -o logfile ls --color=always" and diff the two logfiles.

Well, this looks rather strange. As expected, settings the variable causes large changes as it removes a lot of lstat calls and also removes the color codes from the writes. So there seems to be no obvious explanation, why it becomes slower when doing less...

  # du -sh logfile_nfs*
  1.7M    logfile_nfs
  668K    logfile_nfs_exported
However, the strace -c output looks kinda different:

With setting the variable: https://bin.disroot.org/?149fa91c08b27312#0w9O6BAWNEEC4SUXEb...

You pasted the same link for both cases. Can't tell what's going on.
